Rheumatoid arthritis primarily affects the working-age population and may cause key functional and work limitations. As the disease progresses, individuals become increasingly unable to conduct daily activities, which has a substantial personal and socioeconomic impact. Fairly recent prior studies showed that patients with RA stop working 20 years earlier than age-matched controls. Factors related to sociodemographic, clinical, care and disease profiles might affect the loss of work capacity. The purpose of this study was to assess the factors associated with the prevalence of working patients with rheumatoid arthritis in the municipality of Blumenau.
A cross-sectional, population-based study was conducted between July 2014 and January 2015, with 296 individuals aged 20 years or older, male and female, living in Blumenau, Santa Catarina state, Brazil, and diagnosed with rheumatoid arthritis according to the 1987 American College of Rheumatology criteria. The prevalence of working patients with RA was assessed by employment status self-reporting during the interview. The chi-squared test, Wald test and Poisson regression analysis were used to test the possible associations between the independent variables and outcome.
The prevalence of working patients with rheumatoid arthritis was 44.3%. Patients aged 20 to 59 years had a 90% higher prevalence of outcome than subjects aged 60 years or older. The prevalence of working patients was 132% and 73% higher among individuals with low income and high functional disability, measured using the Health Assessment Questionnaire (HAQ), respectively.
The prevalence of working RA patients was highest among adult patients with low income and high functional disability. The first variable is directly related to the individual characteristic, the second reflects the socioeconomic context of the patient, and the third reflects the degree of disability caused by the disease, which may be modifiable by health professionals.
类风湿关节炎主要影响劳动年龄人群，可能导致主要功能和工作受限。随着疾病的进展，个体越来越无法进行日常活动，这对个人和社会经济都有重大影响。相当近期的先前研究表明，类风湿关节炎患者比同龄对照组提前 20 年停止工作。与社会人口学、临床、护理和疾病特征相关的因素可能会影响工作能力的丧失。本研究旨在评估与布卢梅瑙市类风湿关节炎患者工作能力相关的因素。
这是一项横断面、基于人群的研究，于 2014 年 7 月至 2015 年 1 月进行，共纳入 296 名年龄在 20 岁及以上的男性和女性，居住在巴西圣卡塔琳娜州布卢梅瑙市，根据 1987 年美国风湿病学会标准诊断为类风湿关节炎。通过访谈时的自我报告评估有工作的类风湿关节炎患者的患病率。使用卡方检验、沃尔德检验和泊松回归分析检验了独立变量与结局之间的可能关联。
有工作的类风湿关节炎患者的患病率为 44.3%。20 至 59 岁的患者比 60 岁或以上的患者发生该结局的可能性高 90%。收入低和健康评估问卷（HAQ）测量的功能残疾程度高的患者，工作的类风湿关节炎患者的患病率分别高 132%和 73%。
有工作的类风湿关节炎患者的患病率在收入低和功能残疾程度高的成年患者中最高。第一个变量与个体特征直接相关，第二个变量反映了患者的社会经济背景，第三个变量反映了疾病引起的残疾程度，这可能可以通过卫生专业人员进行改变。
